JOHN VALDHEll/I, GF ELZLBETE, NEW' JERSEY, ASSIGNQR TO UNDERWOQD TYPE- WRITER COMPJQNY, OF NEW' 'SICE-K, l?. Y., A CORPGEATION OF TYPETJ'BITING :MACHINE Application led January 12, 192.2.

i o all 'whom t may concern.'

Be it known lthat I, JOHN lVALDHniM,

a citizen of the United States, residing in Elizabeth, in the county or. Union and State ot' New Jersey, have invented certain new and useiul improvements in Typewriting` lijachines, of which. the following a specification.

lThis invention relates to ingiprovements in sound-deadening casings for typewriting machines.

A feature ot the present ,invention is the ,provision of a drawer in the casing, so that the detritus, which` would otherwise accumulate in the bottom of the casing, may be conveniently removed. The drawer may be anranged underneath the framework of the casing and suitably guided.

tinother feat-ure of the invention is the provision of improved means for closing the `slot in the casing' through which the finger-pieces or handles on `the typewriter carriage project, said slot-closing` means comprising, two .oppositely disposed lia-tsoripsfof telt or any other suitable sounddeadening` material, saidst-rips having abutting vedges dispo-sed substantially at right angles to their other edges by which they are Vtast-cned to the casing. lllith this arrangement,a greaterlocal yield of the slot-closing devices is anorded.

,A Yfurtherfeature of the invention is the provision of' amargin-release key supported on fthe cove-r of the casinggsaid liey being so located that the margiirrelease mechanism ofthe typewriting machine may readily be operated from the exterior ot the casing.

YStill another feature ofthe invention resides inthe provision ot' a carriage-rebase key which is horizont-ally disposed and supported on a detachable carriage-return iin- .g'erpiece7 said hey having at its rear end a cam to engage the usual carriage-release fle'ver .on the typewriter carriage.

llinother feature of the invention resides in the construction ot-thc 'front wall ot the casing', whiclrlias a. main section which in- ,tersects the keyboard ot the machine, and `is provided with a depressed section to ei:- `vtend behind the upper row ot keys in said lieyhoard. ,that all et wir". keys may 'be vninnated from he este?! nl the casing'.

`Elerial No. 528,703.

The front wall may be in the form of a detachable plate having a rectangular opening; through which the keyboard section extends, the opening being high enough to clear the top row oit keys as' the plate is moved rearwardly `over the keys toward the casing. A separate plate may he provided, which, in eli'ect, t'orms a continuation ot the depressed section oit' the iront plate to close the space behind the keys. V

Other features and advantages will hereinafter appear'.

The invention is herein shown as applied to a Remington typewritingr machine, which may be like that disclosed in the patent. to G. A. Seib, No. 1,342,466, dated June S, 1920. The machine comprises a main trame 10 having a foi-wardly-extcnding keyboard section 11 with tvpeflreys 12 and tabula-torkejfs 13 arranged therein. The type-keys, when depressed, operate hey-levers 14 to swing type-bars 15 to cause types 16 to print `against the front tace ot a platen 17. The platen is revolubly mounted in a carriage 18 and may be operated by a line-space handle Q0 comprising a roclsshatt 21 having a` bearing in a block 22 secured to thecarriage and having the usual line-spacing` mechanism including)T the lino-space pawl 23 connected therewith to revolve the platen. The carriage travels on front and rear guide-rails 24 and 25, respectively, and is under the control ot' escapement mechanism omn'ising' a pinion 2G meshing with a feedraclr 27 pivotally mounted on said carriage, the escapement mechanism being operable in. the usual way by the operation of any one ot the type-liens.

Carriage-rdense 30 and 9,1. are proT vided at the right-hand and left-hand ends of the carriage, each key being pivotally mounted on a shouldered screw 32 threaded into end bars 33 et the carriage. Each release key has a rearward extension 234 to raise the rack out of mesh with the pinion the release key is depressed against the tension of the usual return spring (not shown).

A margin-release or line-lock-release key 35 is pivotally mounted on the front rail 2s*- in the usual manner and is actuable to permit the carriage to be moved into the right-hand or left-hand marginr which is determined by the right-hand and letthand margin-stops 86 and 37, respectively.

A ribbon-color shift-key is provided at the front of the machine and secured to a rock-shaft l to which is connected the usual ribbon-shifting mechanism (not shown). rlhe shaft il is supported at its forward end in a bracket i2 secured to the left-hand one of the forward corner posts 4-3 of the machine. rllhe bracket 42 has an extension to form an indexplate 4&4- by which, with the aid of a pointer ton the shaft 4l, the ribbon-vibrating mechanism may be set to bring the black or red lield of a ribbon (not shown) to the printing point.

The sound-deadening casing comprises a body-part and a coif'er-part 51 which may be swung upwardly about a liii'ige 52 at the back of the casing to give access to the inachine within the casing.

To enable the machine tol be placed within the casing the body-part 50 may be provided with a front wall in the :torni et a plate 53 which may temporarily be removed from the casing. The machine may then be set down into the casing with the cover in its raised position. rllhe machine located within the casing by meansI of lugs :Zi/lextending inwardly from the side walls oit the body-part, said lugs having holes into which the rear feet 57 ot the machine are placed. The front plate 523 is provided with a rectangular opening 58 (Figure il), so that it may be slipped over the keyboard section ll and attached to the front of the casing in any convenient manner,l as by screws 60, the upper edge of the rectangular opening 5S beinghigh enough so as not to interfere with the upper bank of keysV (tabulator-keys 13) while being assembled on the casing. To close the open-- ing between the upper end of the rectangular opening 58 and an upper extension 6l o'f the usual key-lever guide-plate 62, there i-s provided a separate removable plate 63. lt will be understood that this plate may be positioned on the frame of the machine prior to the assembling of the front plate 53 en the casing, and that it is held in place by means .of .overlapping edges 64C and 65 (Figure t) of a felt lining 66 secured to said plate 63. To close the opening between a vertical extension G7 oit the guide-plate 62 and a vcross-bar 68 formed at the bottom edge of the front plate 53, there is provided a felt strip 70 which may be secured to the cross-bar 68, the upper end thereof engaging the lower end of the guide-plate By an inspection of Figures l and il, it will be seen that the main portion 7l. of the front plate 58 is substantially in the same plane as the downward extension 67 of the key-lever guide-plate. viNith this arrangement, sulicient space is provided in front of the forward feet 72 of the typewriting machine for a cross-bar 73 cxtending beneath the trame of the machine which joins the two end walls 55 of the body-part of the casing. Thus it will be seen that the plane in which the main part of the front wall is disposed intersects the keyboard of the machine. In order to provide clearance for the keys l2 and 13 or's the keyboard, the front wall of the casing has an indentation 74e or pan-like depression formed by an indented portion 75 joined to the main portion 7l by portions 75 slanting rearwardly toward the indented portion 75 which lies in a plane behind the upper bank of keys 13. The front plate may be lined with a layer 77 of sounddeadening material, such as felt, which may be reduced in thickness at its ends to lit against the front corner posts -ftli y Provision is made to avoid the necessity' ot removing the ribbon-shift key fill when attaching the casing. For this purpose, the front wall of the casing is provided with an opening 8() to tit over said key. rlhe felt lining 77 is provided with radial slits Si at the opening 80 to permit the pension et a hole 79 in the telt when the key passes therethrough, the sectors 82 formed between the slits springing back to close the openingin the :trout wall atter the plate has been positioned. The open ing or hole in the front plate is provided with an upward extension 83 to enable the bichrome index-plate t to be viewed from the exterior of the casing, the extension of said hole being wide enough to permit free movement of the indicator 45 (Figure et).

To enable the margin-releasing mechanism to be operated from the outside ot the casing, there is provided a finger-piece or key 85 at the upper end of a plunger 86 which may be depressed to engage the margin-release key 35 supported on the machine trame. The finger-piece 85 is supported on the cover of the casing, and is guided in said cover and in a suitable bracket Si) secured to the under side of said cover. et flat spring 87 is provided to restore the finger-piece 85 to normal position; said flat spring being secured .to ,the :undr side ot nii-67,558

the coverand being termed at its free end to forni prongs E88 `which engage .in slots in Ythe plunger ot' the `finger-pie@e.

To perm-it the carriage to be moved freely from side to side Without interfe-izence by Various handles, including the linespace handle -20 on the carriage, there is provided a slot 90 which extends along, the front ot Ythe casing, and is `formed between .the upper edge ofthe front wall of the body-part and .the lower edge of the front Wall of the cover 91, throughout the entire length thereof, the rock-shaft 21 of the line-space handle extending forwardly through said slot, so that the linespaee handle may be operated from :the outside of ,the casing.

To llreep the slot elosed :to prevent emission lof sound from the casing, there are provided .two \,ce.- opcretini;v devi-ces V92 and ,opptr sitely disposed and each conrprising` a hat strip 9st `of sound-deadenng material, such as telt. Each `strip is rein-forced by a flat lstrip @5pt-resilient materiahsuch as rubber to giye springiness to the rslotrlosing devices. 'The free edges of the telt strips 94rieaetend su-bstantially at right angles to their other edges which :they lasten .to the casing when the eener is in its lowered position. Als the :cover is opened, the telt strips tend to straighten tourt. It is desir-able, however, to keep said strips kinlced slightly as indicated in Figure 3, so that they will readily fold against ,each .other while the cover is heilig lowered. Todo this, ,the upper .edge

i `ol the front `Wall and the lower edge ot the front IWall 91 of .the coue i' n1ay he provided `with `i-n-,Wardlyrentending ribs 96 ich hear against the strips Self The telt strips 94 lmay beheld with ,their .reinforcing strips between two 1bars 917 and `9,8 cured ,to teach other Yhy riyets 99 to form units held in place by ineens oit screws r100 so .that they may readily vhe detached 1to be replaced lWhenthe .felt strips .become Worn. lt will he seen that, with this construction, the telt stripslend themseliqesto `a greater localyield which is necessar i', due `tothe size of the rocksshat 21 of the line-.space handle, which is much greater as compared with .the thiclnoess of the `handles heretofore used .in 'connection with sound-deadeniing iasiugs.

Vflic carriage may :be returned by a lcarriageareturn .fingeipiece i101 projecting out of the casingl through the slot 90 and from a body-part 102 ,thereof rsecured to 4the carriage by the shouldered screw 32 and a shouldered screw 103.

To enable fthe carriage to be released fromthe outside of the casing, there is pro- `vided a carriage-release key 109 mounted on the vforward end .of a plunger 10st, :the latter being slidingly supported ion the carriagereturn. handle 101, and held thereon by means et shoulclered screws 10,5, Said plunger has at rearfend a `anni (1.015, so

that, when the release key 100 is pushed :in- Wardly, the cani engages the carriage-release key 31 on the carriage to depress the latter and release the rack from `the control of the escapeinent mechanism. The carriage may then the located at the desired position, it being controlled at this time `hy the carriage-return handle 101.

The detritus troni the platen collects in the bottom Aof the casing, which is provided i with a floor 107 comprised preferably ot felt secured to the bot-toni ot the casing` by screws 108. To facilitate the removal ol the detritus, a receptacle or drawer 110 may Vbe provided, which is herein shown as located beneath the body-part lof the casing, and is received in a cutout 111 iny the felt Hoor. A tingenpiece 112 is located `beneath the keyboard of the machine and extends considerably `foi-, fard from the drawer lill, so that it may readily be grasped by the typist to WithdrawY the receptacle from the casing. It vrill be understood that, in assembling the casing' around the machine, it is desirable to assemble the iront plate prior .to inser ,ingr the drawer, ,so as ,to prevent intel-terence of said plate with the top edge ot the trout of :the drawer, which overl-aps the :tuent plate slight-ly (Figure 1),.
